Question about painkillers for dentistry

Previously, an injection site was just numb from the pain medication, but you felt pain, just less, and after the procedure there were rather painful sensations, half of the face sagged. But when was the last time in dentistry, I was injected with something, from which the sensitivity at the injection site was just ZERO, and my face wasn’t dumb, I talked calmly, but I didn’t feel anything, I just lay there and enjoyed it, and after the procedure there were no sensations and there were no scaffolds, just got up and went home.
